How can Trump declare an emergency?

But Congress also gave itself the power to terminate an emergency declaration if both the House and Senate vote to do so.

However, the president could then veto their resolution, and it’s unlikely either chamber could reach the two-thirds majority necessary to reverse a veto.

What are both sides saying?

Sen. Lindsey Graham (R-SC), an ally of the president, has been an ardent supporter of declaring a national emergency.

Not all Republicans feel the same way.

"I have real concerns about it, but I'm not gonna start talking about the floor strategy and how I'm going to vote and how the House is going to vote until we get there, and I hope we don't get there," Sen. Roy Blunt (R-MO) told NPR.

"Having gone to Congress repeatedly having not gotten his way with them ... you can't simply throw your hands up and say, 'Ah, you know my commander in chief powers now will be invoked'" to declare an emergency, said Russell Riley, a presidential scholar at the Miller Center at the University of Virginia.
